Description

Die Erfindung betrifft einen Mobilkran, dessen auf einem Fahrgestell angeordneter Oberwagen den Hauptausleger sowie die Gegengewichte und die Verspannungen für den Hauptausleger trägt.The invention relates to a mobile crane whose on a chassis arranged superstructure carries the main boom as well as the counterweights and bracing for the main boom.

Derartige Mobilkrane sind aus der Praxis bekannt, wobei als Fahrgestell, insbesondere für Kräne höherer Tragkraft, Raupenfahrgestelle verwendet werden.Such mobile cranes are known from practice, with the chassis, can be used in particular for cranes with a higher lifting capacity, crawler chassis.

Eine Erhöhung der aufzunehmenden Lastmomente ist bei diesen Mobil kränen nur bedingt durch Änderung der Gegengewichte möglich.An increase in the load torque to be absorbed is necessary with these mobile cranes only possible to a limited extent by changing the counterweights.

Aufgabe der Erfindung ist es daher einen Mobilkran der eingangs genannten Art derart auszubilden, daß er im Normalfall für die für ihn vorgesehene Tragkraft einsetzbar ist und andererseits mit wenigen Veränderungen auch größere Lastmomente bewältigbar sind.The object of the invention is therefore a mobile crane of the type mentioned at the beginning Kind to train in such a way that he normally works for him for him intended load capacity can be used and, on the other hand, larger load torques can be mastered with just a few changes.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale, wobei sich eine Ausgestaltung aus dem Anspruch 2 ergibt.This object is achieved according to the invention by what is specified in claim 1 Features, one embodiment resulting from claim 2.

Der besondere Vorteil der erfindungsgemäßen Lösung ist in der Teilung des Oberwagens in Bug- und Heckteil zu sehen, die durch ein Oberwagendistanzteil zu einem wesentlich verlängerten Oberwagen wieder zusammensetzbar sind.The particular advantage of the solution according to the invention is the division of the superstructure can be seen in the front and rear sections, which are made possible by a superstructure spacer can be reassembled into a significantly lengthened superstructure.

Auf diese Weise läßt sich der Abstand zwischen dem den Ausleger tragenden Bugteil und dem die Gegengewichte aufnehmenden Heckteil vergrößern, so daß für spezielle Lastfälle ein größeres Gerät, das höhere Lastmomente aufnehmen kann, zur Verfugung steht, während im Normal fall der Mobilkran hinsichtlich der Abmessungen keinen größeren Platzbedarf hat.In this way, the distance between the boom supporting Enlarge the front part and the rear part receiving the counterweights, so that for special load cases a larger device, the higher one Can absorb load moments, is available, while in the normal case the mobile crane does not require a large amount of space in terms of dimensions Has.

Die Erfindung soll nachfolgend anhand der Figur erläutert werden, wobei diese eine schematische Darstellung des mit einem Oberwagendistanzteil veränderten Mobilkranes zeigt.The invention will be explained below with reference to the figure, wherein this shows a schematic representation of the mobile crane modified with a superstructure spacer.

Der Oberwagen besteht aus einem Bugteil 1, das in üblicher Weise den Hauptausleger 2 trägt. Dieses Bugteil 1 des Oberwagens verbleibt auf dem Raupenunterwagen 3, also dem Fahrgestell, während das Heckteil 4 des Oberwagens mit den Gegengewichten 5 auf einem zusätzlichen Fahrgestell 6, vorzugsweise ebenfalls einem Raupenunterwagen, aufsetzbar ist und die Verbindung Bug- und Heckteil durch, im dargestellten Fall, eine geschweißte Rahmenkonstruktion 7 erfolgte.The superstructure consists of a front part 1, which in the usual way Main boom 2 carries. This front part 1 of the superstructure remains on the crawler undercarriage 3, so the chassis, while the rear part 4 of the superstructure with the counterweights 5 on an additional chassis 6, preferably also a crawler undercarriage, and the connection of the front and rear parts through, in the case shown, a welded frame construction 7 took place.

Es ist ohne weiteres ersichtlich, daß durch diese Verlängerung des Oberwagens der Kran in der Lage ist, wesentlich höhere Lastmomente aufzunehmen, wobei dann allerdings der Platzbedarf des Gesamtgerätes größer ist.It is readily apparent that this extension of the The upper structure of the crane is able to absorb significantly higher load torques, but then the space requirement of the entire device is bigger.

Für die Normal fälle, bei denen Bug- und Heckteil direkt miteinander verbunden sind, benötigt der Mobilkran allerdings nur den für ihn vorgesehenen geringen Platz.For normal cases where the bow and stern sections are directly connected to each other are connected, the mobile crane only needs the small space provided for it.
